docs: document script hot-reload mechanisms for all script types

 - This allows complex request/response structures (e.g., an object containing properties and a list of nested objects).
 - Template attributes retain the simpler four-type system. The extended types apply only to Inbound API method definitions and External System Gateway method definitions.
 
+## Script Compilation & Hot-Reload
+
+API method scripts are compiled at central startup — all method definitions are loaded from the configuration database and compiled into in-memory delegates.
+
+### Update Workflow
+
+- Updating a method via the CLI (`api-method update --id <N> --code '...'`) or Management API triggers immediate recompilation (`CompileAndRegister`). The updated script takes effect on the next API call — no node restart is required.
+- Creating a new method after startup: if the method is created but not yet compiled, the first invocation triggers lazy (on-demand) compilation.
+
+### Direct SQL Warning
+
+> **Do not edit API method scripts via direct SQL.** The in-memory compiled script will not be updated until the next node restart. Always use the CLI, Management API, or Central UI to modify API method scripts.

 ## API Call Logging
 
 - **Only failures are logged.** Script execution errors (500 responses) are logged centrally.
